\ 9 Claims. (Cl. 222-173) This invention relates generally to a pressurized con tainer, and more particularly to a pressurized container having a faucet extending therefrom for dispensing fluids.

Containers of the class described are finding increasing use in the merchandising of fluent substances, particularly in the distribution of such substances for home consumption as, for example, beverages and the like. When used for this purpose, a protruding faucet must be provided on the container in order to permit the contents thereof to be easily dispensed. Such a protruding faucet, however, forms a discontinuity upon the exterior surface of the container. When containers of the class described are stacked in a warehouse awaiting shipment to a distribution point, or in a store for display and sale, the protruding faucets cause the containers to take up a great deal of floor space in excess of that which would be required were there no such protruding faucets. Furthermore, when a container of the class described containing a beverage is placed in a home-type refrigerator, its protruding faucet is very likely to interfere with other items commonly kept therein. In addition to causing the container to take up excessive space during storage, the protruding faucet is inherently susceptible to damage which would give rise to possible contamination of the container contents. By providing a guard on the protruding faucet, the likelihood of contamination arising from damage to the faucet is reduced. However, such expedient does not solve the problem of excessive floor space required to ship or store the containers.

A further problem arises when the spout of the faucet is fixed with respect to the container because this results in requiring dispensing of the contents to be done only when the container is in a certain position or attitude. Thus, it is very likely that the attitude of a beverage container for achieving optimum space utility in a hometype refrigerator is incompatible with the attitude required for the spout to dispense the contents.

Much effort has been expended to contribute a container of the class described in which the dispensing means do not hinder either storage of many containers or dispensing from a single container in the manner set forth above, but so far as is known, no successful device of the class described has yet been contributed to the art, and the problems here outlined remain unsolved. It is the object of this invention to contribute a container of the class described in which the provision of a protruding faucet thereon does not present any real obstacle to closely stacking many containers, and to dispensing the contents of the container from any position thereof.

As a feature of this invention whereby the objects thereof are achieved, a faucet is provided on the container that is movable from a retracted position entirely contained interior to the container, to an extended position exterior to the container. By making the faucet rotatable as well as reciprocable, it may be rotated when in the exice tended position until the spout can be used to dispense the contents regardless of the attitude of the container, and it may be rotated when in the retracted position until the spout can be used to lock the faucet in the retracted position. By making the cross-sectional area of the faucet sufiiciently large, the force exerted thereon due to the difference between the pressure internal to the container and ambient pressure will automatically move the faucet from retracted position to extended position after the faucet has been rotated to the position at which the spout effects reciprocal movement of the faucet.

The more important features of this invention have thus been outlined rather broadly in order that the detailed description thereof that follows may be better understood, and in order that the contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will also form the subject of the claims appended hereto. Those skilled in the art will appreciate that the conception upon which this disclosure is based may readily be utilized as a basis for designing other structures for carrying out the several purposes of this invention. It is important, therefore, that the claims to be granted herein shall be of sufficient breadth to prevent the appropriation of this invention by those skilled in the art.

In the drawing:

FIGURE 1 is a perspetcive view of a container equipped with a faucet and made in accordance with this invention showing the faucet in its retracted position with a crowntype closure in place over the faucet.

FIGURE 2 is a perspective view of the container shown in FIGURE 1 with the faucet shown in its extended position with the spout oriented to dispense the contents.

FIGURE 3 is a sectional view showing the internal arrangement of the container shown in FIGURE 2.

FIGURE 4 is a sectional view showing the internal arrangement of the container shown in FIGURE 1.

There is shown in FIGURES 1 and 2, a parallelepiped container indicated generally at 10 having a handle 11 in one side face 12 to facilitate carrying the container, and a recess 13 in an adjacent front face 14 to house the faucet described below. Container 10 carries fluent material 15 under pressure which may be dispensed by means of the faucet. Attached to the interior of container 10 is inwardly extending tube 16 whose axis is equidistant from bottom 17 and side face 18. Tube 16 also projects outwardly from surface 19, which defines the bottom of recess 13, to form lip 2%. Tube 16 thus defines an opening in face 14 into which cylindrical barrel 22 of a faucet 21 is reciprocally and rotatably mounted, as indicated by a comparison of FIGURE 3 with FIGURE 4.

Axial passage 23 forms a conduit for fluent material 15 which is forced thereinto through tube 24 attached to the interior end of barrel 22 by the internal pressure of container 19. The rear portion of tube 16 is enlarged and contains groove 25 for O ring 26 to provide a seal between the tube and barrel 22. The forward portion of barrel 22 is reduced in diameter to define shoulder 27 which limits extension of the barrel when it abuts snap ring 28 engaged in a groove adjacent the forward open end of tube 16.

Valve 29 is disposed at the forward end of faucet 21 coaxial with passage 23 and is operable by button 30 which is spring urged to normally seat valve 29 in closed position. Spout 31 connects with a portion of passage 23 and provides the means by which fluent material may be selectively withdrawn from container 10.

Snap ring 28 has a notch 32 as shown in FIGURE 4, and adjacent this notch, tube 16 has a recess 33 which is sufficiently large to receive spout 31 when faucet 21 is pushed to retracted position. The position of spout 31 in this condition is as shown in phantom lines in FIG- URE 4, and crown closure 34- may then be seated on lip 20 since button 30 is now interior to the lip.

At the factory, faucet 21 is moved to retracted position as described above with spout 31 in recess 33 and rotated in tube 16 by means of knurled knob 36 so that spout 31 is engaged behind snap ring 28 to retain the faucet in retracted position. Crown closure 34 is then placed on lip 20 and the container may be filled as through flush closure 35. The result is a container having no protuberances to interfere with stacking containers in storage, or to interfere with other articles usually found in hometype refrigerators. The appearance of the container is as shown in FIGURE 1 and, as can be readily seen, a minimum amount of floor or shelf space is required by this shape.

Furthermore, closure 34- eifectively seals the faucet so that the contents of the container cannot become contaminated during the time the container is in storage or in transit to the consumer. When in the hands of a consumer, closure 34 may easily be removed in the same manner that a bottle crown closure is removed. By grasping knob 36, faucet 21 may be rotated to align spout 31 with notch 32. The cross-sectional area of barrel 22 is sufficiently large for the force exerted thereon, due to the difference between the pressure internal to container and ambient air pressure external to the container, to then automatically move the faucet from its retracted position to its extended position so that fluent material may be withdrawn. Thus, the portion of barrel 22 exposed to the pressure differential constitutes means that is responsive to such differential for automatically moving faucet 21 from retracted to extended position when the latter is rotated so that spout 31 is aligned with notch 32. In such position, the pressure on the interior of faucet 21 acts to cause faucet 21 to automatically move from its retracted position to its extended position so that fluent material 15 may be withdrawn.

Faucet 21 is constructed so that the free end of tube 24 interior to the container opens in the same direction as the outlet of spout 31. Since the faucet is rotatably mounted in tube 16, turning spout 31 to the position required for dispensing fluent material 15 will necessarily place the free end of tube 24 within the fluent material regardless of what surface the container is resting upon. For example, if the container is resting on bottom 17, the free end of tube 24 is adjacent the bottom when spout 31 is turned to the position required for material to be dispensed; and when the container is resting on side 18, the free end of tube 24 is adjacent that side when spout 31 is turned to the position required for material 15 to be dispensed. By locating the axis of tube 16 equidistant from bottom 17 and side 18, the free end of tube 2 4 will be equidistant from both bottom 17 and side 18 when faucet 21 is turned to the positions described above.

It should be noted that when faucet 21 is in its retracted position with spout 31 engaged behind snap ring 28, and closure 34 is engaged on lip to seal tube 16 and protect contents 115 from contamination, nothing protrudes from surface 14 to interfere with close stacking of many containers. This desirable result arises because surface 19 is recessed sufliciently for closure 34 to lie entirely within recess 13.

Those skilled in the art will now appreciate that by this invention, there is provided a container having a faucet for dispensing pressurized fluent material which nevertheless takes up a minimum of storage space, permits convenient stacking and storage, and safeguards the fluent material against contamination. It will be further appreciated that this invention also provides a container in which a retractable faucet is automatically extendable for permitting dispensing of fluent material from the container in whatever position is most convenient for its storage.
